AI Overviews vs AI Mode: one set of rules

What is each surface?

AI Overviews is a generated snapshot with key information about a topic and links to dig deeper, shown inside an ordinary Google results page when Google's systems decide generative AI can be especially helpful. A person searches as usual and sometimes an Overview appears above the links. Google announced on 14 May 2024 that it would begin rolling AI Overviews out to everyone in the United States. Its own help page says they can and will make mistakes.

AI Mode is a separate place in Search. Google announced it on 5 March 2025 as an opt-in experiment in Search Labs, running on a custom version of Gemini 2.0, and described it as expanding what AI Overviews can do with more advanced reasoning and multimodal input. Google's documentation says it is most useful where a question needs exploration, reasoning or complex comparison, and it supports follow-up questions.

The short way to hold the difference: AI Overviews comes to the searcher, inside results they already asked for. The searcher goes to AI Mode, for a conversation.

Do they follow different rules for sites?

No. Google's Search Central documentation treats them together. There are no additional requirements to appear in AI Overviews or AI Mode. To be a supporting link in either, a page must be indexed and eligible to be shown in Google Search with a snippet. Google adds that no special machine-readable files, AI text files or schema are needed.

They also share a source. Google documents no separate crawler for either; both read the Search index that Googlebot builds. Our own log shows the same thing from the receiving end. In the 30 days to 4 October 2026, attensira.com received 143,601 requests from AI crawlers. None carried a Google AI Overview or Gemini user agent. Googlebot made 189 requests across 80 pages. If you want to know whether Google's AI surfaces can see a page, the question is whether Googlebot can, and whether the page is indexed.

What does a page that works for both look like?

Take a buyer researching project-management tools for a small agency. In ordinary Search they type "best project management tool for agencies" and may see an Overview naming a few tools, a sentence each, with links to the pages it drew on. In AI Mode they ask "which project management tool suits a 12-person agency that bills by the hour and uses Slack", then follow up with "how does pricing compare for 12 seats". Fan-out turns each of those into searches about agencies, time tracking, Slack and per-seat pricing.

A vendor that wants to be cited in both needs the same pages: one that says plainly who the product is for, a pricing page with per-seat figures in text rather than an image, an integrations page that names Slack and says what the integration does, and a comparison page that is honest about where a competitor fits better. None of that is specific to either surface. All of it is specific to the questions buyers ask, which is why the short searches and the long conversations end up citing different pages from the same site.

Can you opt out of one and not the other?

No. Google has added a setting to Search Console that decides whether a site appears in, and helps ground, its generative AI Search features: AI Overviews, AI Mode and AI Overviews in Discover, together. Google says the setting is not used as a ranking signal for ordinary results. There is no documented way to stay in one surface and leave the other.

The older controls behave the same way. nosnippet, data-nosnippet and max-snippet limit what Google may show from a page, in its AI features as in ordinary snippets, and noindex removes the page from Search entirely. Each applies to both AI surfaces at once. If the goal is to keep one passage out of AI answers, data-nosnippet on that passage is the narrow tool; the Search Console setting is the blunt one, and it costs you both surfaces.

Few businesses that sell to people who search should use the blunt one. It suits a publisher whose pages are the product, where an answer that summarises the page replaces the visit. For a company whose pages exist to be found and chosen, leaving both surfaces removes it from exactly the answers its buyers read before they shortlist anyone.

How can you measure each one?

Google now counts appearances. A generative AI performance report in Search Console, rolled out to all sites by 31 August 2026, shows how often your pages appeared in AI features such as AI Overviews and AI Mode, by page, country, device and date. Clicks from those features still sit inside overall Search traffic, under the Web search type. So Search Console can tell you that a page appeared; it cannot tell you what the answer said about you, or who was recommended instead.

That part needs reading the answers. For AI Overviews, a tool can load the results page for each tracked search every day and record whether an Overview appeared, which pages it cited and whether one is yours, keeping "Google showed none" separate from "we could not see one". AI Mode has to be read the same way, as a conversation, and fewer tools do it. Report each surface separately, with the number of days or answers behind every share, and label manual spot checks as such.

How should you report the two?

As separate lines, never one blended score. For AI Overviews: the share of tracked searches that showed an Overview on days when the result could be read, and the share of those that cited one of your pages, each with the number of days behind it. For AI Mode: whatever you read deliberately, with the number of conversations and the date, and Search Console's impression count beside it. Put Search Console clicks underneath both, labelled as all Google Search clicks, because Google does not split clicks by AI feature.

A report built this way can be acted on. When Overview citations fall while AI Mode impressions hold, the short definitional pages need work; when the reverse happens, the comparison and pricing pages do. A single "Google AI visibility" number would show neither.

What should a site actually do?

The same work for both, in this order. Make sure the pages that answer your buyers' questions are indexed and snippet-eligible: no stray noindex, no site-wide nosnippet or low max-snippet left over from an old template, and the Search Console setting left on unless you have decided to leave both surfaces. Write the answer to each important question plainly near the top of the page that owns it, with numbers and their sources in the text. Cover the sub-questions fan-out is likely to generate. And earn mentions on the pages Google already trusts for your category, because both surfaces draw on the same index.

When an Overview cites you, check what it says. An Overview that links your page next to a wrong statement about your product is worse than one that does not cite you, and the fix is usually on the page: a passage that is ambiguous, out of date or silent on the point. What not to do is build separate "AI Mode pages", add special markup for either surface, or publish files Google says it does not need. None of those is a documented lever.
